Marcie Natale's Bio:
Marcie Natale graduated from Millersville University with a BS in Biochemistry and she received her MBA in International Business from Temple. Marcie began her career at Henkel Corporate Research in the organic synthesis department focusing on defoamers, associative thickeners, and emulsion polymerization of green surfactants. In 2001 Marcie joined Cognis to focus on technical marketing, with an emphasis on green and sulfate free surfactants and additives for shampoos & body care. In 2006, Marcie was recruited by Eastman Chemical Company to lead development teams in the personal care segment. She is currently the biocatalysis platform development manager for Eastman. Eastman’s biocatalysis platform was recognized in June 2009 by the EPA. Marcie is a recipient of the 2009 EPA Presidential Award for Green Chemistry in the category of Greener Synthetic Pathways. She continues to develop commercial products by using green chemistry principles.
Abstract for “A Green Process for Innovative Cosmetic Ingredients":
Natural ingredients have always been important in the cosmetics market, while the demand for the use of green processes is becoming more important to both formulators and consumers. While some definitions are still being debated, “natural” typically refers to the source of the raw materials, and “green” refers to the processes used to convert starting materials to a finished ingredient. The Twelve Principles of Green Chemistry, originally published by Paul Anastas and John Warner, have been widely adopted as agency and industry standards. The Principles of Green Chemistry can be readily applied to the manufacture of cosmetic ingredients, with a goal of achieving maximum efficiency and minimal environmental impact. This presentation will review developments in green chemistry technology for producing innovative ingredients, with a focus on a biocatalytic manufacturing process that was recognized in 2009 with a Presidential Green Chemistry Challenge Award.
Eastman’s green biocatalytic process has been used to synthesize a variety of cosmetic esters via enzymatic esterifications at mild temperatures. The esterifications are driven to high conversion by removing the coproduct, usually either water from esterification of an acid or a lower alcohol from transesterification of an ester. The mild processing conditions do not lead to formation of undesirable byproducts that may contribute color or odor. The immobilized enzyme, such as lipase, is easily removed by filtration. The specificity of the enzymatic conversions and the relatively low reaction temperatures minimize the formation of byproducts, increase yield, and save energy. A variety of ingredients produced by this process, and their performance benefits, will be discussed.
